New Mini High Torque Ford 460 Starter - Top Mount

After years of only having rebuilt starters available we are excited to at last offer a truly modern high torque, gear reduction style starter for the once Iconic Ford 460 Pack-a-jet engine applications. The compact body of this unit delivers more cranking power than a OEM starter could ever dream of.

USCG Approved (SAE J1171)

This starter mounts on the top of your 460 ford engines Bell Housing and is a reverse rotation starter, so it can start your standard rotation engine. (* Bell Housing not included)

*FITMENT CAUTION-- Designed for Top mounted starter bellhousing's with a 5-1/4" mounting bolt center to center spacing . This starter requires a 4-1/16" opening. **NOTE** For proper starter engagement installer MUST CONFIRM the distance from the bellhousing's starter mounting flange to the engines flyweel/Flexplate face of the ring gear teeth is 18MM or 11/16*

Used on new model Bravo's  serial number 2A514803 and up. Older models before that serial number use #125-40020.

At last a superior fix for water supply to your boats inner transom assembly that feeds your engine its water supply. Corrosion in know to cause massive restrictions, restricting the supply of water to your engine sea water pump. This handy invention provides a new stainless steel fitting provision along with a hose and the necessary gaskets and clamp to permanently fix the issue. This kit replaces the OEM Mercruiser # 32-8M0124395

O2 Spacer, For Common Log Style Exhaust manifolds

This Unique 1" thick adapter plate provides an installation option for retro fitting a Oxygen sensor and or air fuel ratio gauge for tuning purposes Into the most common Log Manifold style exhaust systems. The part is manufactured from Aluminum and is not treated with any corrosion resistance. Designed to accept popular 18MM O2 Oxygen sensors.

TECH NOTE: Will O2 Sensors Work In marine exhaust systems?

YES FOR TUNING but they have limitations as water / moisture is a byproduct of combustion. Often boaters find there is moisture in their exhaust system that have collected or made their way inside of what is better known as the "DRY" exhaust stream of their exhaust system. Anything from steam like to little water droplets about 1/32" all around the inside of the exhaust. This is because water IS a by product of combustion. same thing you see on a cold morning behind cars. sometimes you see water dripping out.

Don't take our word for it ask a real rocket scientist: https://www.grc.nasa.gov/www/k-12/airplane/combst1.html

This is why O2 Sensors are great for tuning but have a limited long term life span unless protected by Catalytic converters like on New Marine engine offerings. So you know gas is known as a hydrocarbon based fuel. And we all know what hydro means WATER.
